J1.01.2.2 Whole Number Mixed Operation Level 2

https://www.mathaddiction.org/j1-01-2-2

There are quite a few different variation of questions, at least 8, in each J1.01.2.1 and J1.01.2.2 which also took sooooo long to put them together.

The other reason why it took so long is due to the complexity of handling difficulty level. The generated questions shouldn't be too hard nor too easy, so on top of the different questions, it should cover the different difficulties from easy, medium to hard, say maybe by the allocation of 50%, 30% and 20% respectively in general.

Hopefully this can help someone or at least have some fun.

If you found any bugs or have any suggestions can please contact through the contact page or leave a comment down here.

Thanks~!

J1.01.2.1和J1.01.2.2中各自都有很多不同结构的问题，至少有8种，所以花了很很很很很长时间才能将它们放在一起。

花费这么长时间的另一个原因是由于要处理难度级别的复杂性。 生成的问题不应该太难也不能太容易，因此除了不同的问题外，它还要涵盖从容易，中等到困难的不同难度级别，大致上分别分配在50％，30％和20％。

希望这可以帮助某些人或至少从中获得一些乐趣。
